Title: Instrument for determination of weight concentration and radioactive concentration of aerosols

Abstract: 1,216,561. Monitoring radioactive particles. V. G. BABICH, A. K. KURSKY, K. P. MARKOV, N. V. RYABOV and K. N. STAS. 16 Jan., 1968, No. 2347/68. Heading BIT. [Also in Division G1] An instrument for determining both the particle concentration by weight and the radioactive concentration of an aerosol, comprises a conduit 2, through which an aerosol sample is drawn so as to pass through a filter 4, a radioactive source 6 positionable in the conduit upstream of the filter, and a radiation detector 8 located dawnstream of the filter. In measuring the radioactive concentration of the aerosol particles deposited on a strip 4 when a sample is drawn through by pump 12, the source 6 is in its retracted position and the radioactivity of the deposited particles is measured by detector 8, connected to a recorder 10, and meter 11. The measurement of the particle weight concentration comprises two steps. Firstly, a clean filter is moved over the port 3. The α-particle source 6 is moved into the conduit and the radiation transmitted by the filter, representative of the filter thickness, measured by detector 8 and recorder &c. The source 6 is retracted and the aerosol sample drawn through the filter. The source 6 is replaced and a second measurement carried out. The intensity of the source 6 is much higher than that of background radioactivity residing in the deposited aerosol particles. The use of an alpha particle absorbing collimator 9 further reduces the effects of background on the measurement. The first measurement is subtracted from the second 'to provide a value proportional to the deposition thickness and thus the particle weight concentration.

Abstract: 914,743. Bearings. BARDEN CORPORATION. Jan. 26, 1959 [Feb. 10, 1958], No. 2697/59. Class 12 (1). A dynamic bearing unit has a rotatable shaft in a bearing carried by a rotatable support which is coaxial to said shaft. The support is rotated about its axis by a rotor attached thereto and co-operating with an energized stator. In an embodiment, a gyroscope 10 has a housing 12 and a rotor 14 supported by identical bearing units 16, 18. Each unit has a shaft 20 mounted in double-bearings 30, 32 carried by a rotatable support 38, the outer and inner races being attached to the support 38 and to the shaft 20 respectively. The rotatable support 38 is mounted in double-bearings 48, 50, carried by a housing 66. The bearings 30, 32 and 48, 50 are retained by annular plates 34, 56 secured to the support 38 and housing 66 respectively. An annular permanent magnet 42, having six poles 44, for example, is fixed to the support 38 by adhesive 46 &c. and a spool 68, having three axially-extending poles 70, for example, is mounted in the housing 66. The poles 70 surround the magnet 42 and are energized by a coil 76, which is carried by the spool 68 and is supplied with electrical energy through conductors 78, 80. In operation, the outer races 26, 28 of the bearings 30, 32 are oscillated so that the net frictional torque applied to the shaft 20 is substantially zero. The oscillations are effected by a low-frequency alternating current supplied to the coil 76 which produces an alternating magnetic field in the poles 70 to cause alternative alignment with the north and south poles of the magnet 42. In a modification, the coil 76 is energized by pulsating direct-current acting against a spring. The bearings may be ball, roller or fluid &c.

Abstract: 1,124,221. Electric signalling. GESELLSCHAFT FUER KERNFORSCHUNG M.b.H. Jan. 19, 1967 [Jan. 21, 1966], No. 2805/67. Heading G1N. Sensors 1, such as temperature or humidity dependent resistors, are successively sampled by pulses from delay units 2, each unit 2 consisting of a normally non-conducting transistor 3 connected between voltage supplies 6, 8 and to a voltage bias 12, a negative pulse supplied to a capacitor 14 in the base circuit being differentiated and its rising edge supplied to the transistor base 9 thereby rendering it conductive for a period determined by circuit values and the degree of saturation of the transistor. The collector 4 thus produces a negative going pulse which is applied: to one end of the resistive sensor 1; to the next stage capacitor 14 which responds to its rising edge to energize the next sensor; and to a signal line 16 through the diode 15. The other end of the sensor is connected through a diode 17 to a signal line 18 and the magnitude of the voltage pulse across the sensor, if any, appears between the lines 16,18 and is measured at a remote control station. The sequence of measurements is initiated by a start pulse from the control station. To facilitate identification of sensor output pulses at the receiving station, m pairs of signal lines 16, 18 may be provided, the first being connected to stages 1, m + 1, 2m +1, etc., the second pair being connected to stages 2, m + 2, 2m + 2, etc., and so on. If only one pair of signal lines 16, 18 is provided, identification of the output pulses is improved by inserting passive delay elements between the units 2. The sensors may be associated with a pipe-line, and a leak is thus signalled in magnitude and position to a control station.
